Hypericum galioides var. cubense Grisebach, Catalogus Plantarum Cubensium, 

 1866, p. 39. 



About 1850, Jose Blain, Nos. 12Q, 150 (Millspaugh, Botanical 

 Series, Field Columbian Museum, I, 1900, p. 430); probably to this 

 variety also belongs the report by Achille Richard, in Sagra, Historia 

 Fisica, Politica y Natural de la Isla de Cuba, X, 1845, p. 97, based on 

 the collections of A. H. Lanier, 1831. Richard lists this as Hypericum 

 galioides, but notes that upon comparison of the specimens from the 

 Isle of Pines with material from North America differences are plainly 

 evident. Lanier's specimens appear to answer to the description of 

 the variety cubense as later published by Grisebach. General Distri- 

 bution: Cuba and the Isle of Pines. 



468. Hypericum aspalathoides Willdenow, 



Hypericum aspalathoides Willdenow, Species Plantarum, III, 1805, p. 1451.
